OK, when my wife brings home a nice steak, I usually fire up the grill. Even in the dead of winter turbo the eskimo is grilling. After watching Alton Brown's video segment on steaks, we decided to try his method, so when she showed up after work with a nice 1" thick strip steak we gave it a go. I think my grill is going to see a lot of down-time this winter - the steak was THAT good. The method:
Preheat your oven to 500 deg and put a heavy cast-iron skillet on a burner turned to High to preheat for at least a few minutes. Dust the steak with Kosher salt and cracked peppercorns on both sides and pat that in with a couple of dashes of high-temperature oil (peanut oil is my favorite so we used that). Put the steak in the super-hot skillet for 30 seconds on each side and don't touch it in the meantime, so a nice crust can develop on the seared surfaces, then transfer the skillet and steak into the oven. We let ours cook for 1min,15sec/side in the oven because we both prefer steak rare - Brown suggested 2 minutes per side. When the oven time is up, put the steak on an inverted dish in a larger platter, so any grease/juices will run off, and lightly cover the hot steak with aluminum foil for 3 minutes to allow the steak to "relax" before serving. The steak was perfectly done, juicy, and tender.
NOTE: Just like when grilling, never handle your steaks with a fork - always use a large pair of tongs to avoid penetrating the meat and letting the juices out. That steak and a nice green salad made for a perfect supper.
